I honestly don't know sorry Willraja, I haven't been following it too closely today due to being busy except for looking at a few model products. I was just commenting on how it can be hard to tell if a marginal system's a TC or not just by looking at an MSLP chart.

Tropical Cyclone Outlook for Coral SeaIssued at 2:30 pm EST on Sunday 1 April 2018for the period until midnight EST Wednesday 4 April 2018.Existing Cyclones in the Eastern Region:None.Potential Cyclones:

At 2:00pm EST Sunday, ex-tropical cyclone Iris was located near latitude 15.5 degrees south, longitude 149.3 degrees east, about 410 km east-northeast of Cairns. The low is currently moving south-southwest at about 5 km/h.The system is likely to remain slow moving for much of today before adopting a more southwesterly track and moving closer to the tropical or central Queensland coast on Monday and Tuesday.The system is expected to remain a subtropical low today and tomorrow, however the environment becomes more favourable on Tuesday.

Likelihood of a tropical cyclone in the Eastern Region on:Monday:LowTuesday:ModerateWednesday:Moderate

Loving each new model run that comes out. It's like they are trying to out do the craziness of the last one. We may be watching this thing in the same place in a weeks time after it's done another loop de loop. Crazy stuff

This system could eventually go down as one of the most unpredictable and longest lived ones in the Coral Sea in years (much of it as an ex-TC) if it followed the "staying out to sea" scenarios. But if it crossed early, its lifespan will be shorter.

I was always under that impression due to the fact lower pressure has air rushing in to it from higher pressure, that the lower the pressure the faster the air is moving into the centre the faster the winds. So that is usually the case but not 100% of the time. Glad that fact has been cleared up with me.
